Epidemiological Characteristics of School Playground Injuries.

Reports of children's play-related injuries have remained stagnant according to epidemiology studies of the past 3 decades. This article provides a unique look into the context of playground injuries within an entire school district, demonstrating the prevalence of these injuries. This study reports that playgrounds are the leading location of school injury, comprising one-third of all elementary school injuries. This study found that while head/neck injuries were the most commonly injured body region within the playground environment, the proportion of head/neck injuries decreased with age, whereas the proportion of extremity injuries increased with age. At least 1 upper extremity injury required outside medical attention for every 4 that were treated on-site, making upper extremity injuries roughly twice as likely to require outside medical attention as injuries to other body regions. The data in this study are useful for interpreting injury patterns in the context and evaluation of existing safety standards for playgrounds.

A Cross-Sectional Study of Tampering in Xtampza ER, an Abuse-Deterrent Formulation of an Extended-Release Opioid, in a Treatment Center Population.

BACKGROUND AND OBJECTIVE: While the current landscape of opioid use disorder (OUD) is complicated by the increase in use of non-prescription opioids, prescription opioids continue to be frequently used in non-medical ways. In response to this abuse, pharmaceutical companies have developed abuse deterrent formulations (ADFs) for extended-release (ER) opioids. To test the effectiveness of Xtampza ER ADF (oxycodone myristate) at reducing tampering, its rate of tampering in a treatment-center population was compared to immediate release (IR) single entity (SE) oxycodone, other ER oxycodone opioids, and ER oxymorphone. METHODS: Data were collected between the third quarter of 2018 and the third quarter of 2021 from individuals entering nationally distributed opioid treatment programs. To determine odds of tampering with Xtampza ER compared to each comparator, a logistic model was fit with a random intercept allowing for multiple drugs in each subject. Within-subject correlation was assumed to have a compound symmetric relationship. RESULTS: Overlap among the categories of drug tampering was high. Logistic regression analyses found that oxycodone myristate had lower odds of tampering when compared to both IR SE oxycodone (OR = 0.23 [95% CI 0.11, 0.50], p = 0.0002) and ER oxymorphone (OR = 0.30 [95% CI 0.14, 0.67], p = 0.0038). Oxycodone myristate was not significantly different from other ER oxycodone opioids (OR = 0.5 [95% CI 0.24, 1.03], p = 0.0612). These findings did not change when the estimates were adjusted for age and sex. CONCLUSIONS: Drugs employing ADF technology may reduce the likelihood of tampering when compared to non-ADF formulations in a treatment-center population, which represents an opportunity for intervention in OUD among those still requiring pain management.

Reimagining spaces where children play: developing guidance for thermally comfortable playgrounds in Canada.

SETTING: Planning and designing thermally comfortable outdoor spaces is increasingly important in the context of climate change, particularly as children are more vulnerable than adults to environmental extremes. However, existing playground standards focus on equipment and surfacing to reduce acute injuries, with no mention of potential negative health consequences related to heat illness, sun exposure, and other thermal extremes. The goal of this project was to develop proposed guidelines for designing thermally comfortable playgrounds in Canada for inclusion within the CAN/CSA-Z614 Children's playground equipment and surfacing standard. INTERVENTION: The project to develop guidance for thermally comfortable playgrounds was initiated with a municipal project in Windsor, Ontario, to increase shade, vegetation, and water features at parks and playgrounds to provide more comfortable experiences amid the increased frequency of hot days (≥30°C). The lack of available information to best manage environmental conditions led to a collaborative effort to build resources and raise awareness of best practices in the design of thermally comfortable playgrounds. OUTCOMES: A group of multidisciplinary experts developed technical guidance for improving thermal comfort at playgrounds, including a six-page thermal comfort annex adopted within a national playground and equipment standard. The annex has been used by Canadian schools in a competition to design and implement green playgrounds. IMPLICATIONS: Both the technical report and the thermal comfort annex provide increased awareness and needed guidance for managing environmental conditions at playgrounds. Thermally safe and comfortable play spaces will help ensure that Canada's playgrounds are designed to minimize environmental health risks for children.

RéSUMé: CONTEXTE: À l'ère des changements climatiques, le confort thermique n'a jamais été si important pour la planification et l'aménagement d'espaces extérieurs, surtout car les enfants sont plus sensibles que les adultes aux chaleurs brûlantes. Cependant, les normes qui encadrent actuellement les aires de jeu s'articulent autour d'une logique de prévention de traumatismes. Elles portent donc principalement sur les équipements et leurs revêtements plutôt que sur les conséquences des canicules, des malaises liés à la chaleur et des insolations. L'objectif du présent projet est de rédiger un projet de directives pour favoriser le confort thermique des aires de jeu au Canada et d'intégrer ces directives à la norme CAN/CSA-Z614 Aires et équipements de jeu. INTERVENTION: Les origines du projet remontent à une action municipale à Windsor, en Ontario. Celle-ci avait pour but d'augmenter la quantité de zones d'ombres, de végétation et de jeux d'eau dans les parcs et les aires de jeu en vue de favoriser le confort thermique vu la fréquence croissante des canicules (≥30°C). Le constat de lacunes d'informations autour de la gestion des conditions écologiques a suscité une concertation pour créer des ressources et faire rayonner des pratiques d'aménagement optimales pour l'amélioration du confort thermique des aires de jeu. RéSULTATS: Une équipe transversale d'experts a rédigé des directives techniques pour améliorer le confort thermique des aires de jeu, ainsi qu'une annexe de six pages sur la question qui a été intégrée à une norme nationale. Dans le cadre d'un concours, des écoles canadiennes se sont servies de l'annexe comme référentiel pour penser et aménager des aires de jeu vertes. IMPLICATIONS: Le rapport technique et l'annexe mettent en valeur le besoin d'encadrer la gestion des facteurs environnementaux des aires de jeu. L'amélioration du confort thermique de ces espaces et la réduction des risques environnementaux permettent de protéger la santé des enfants au Canada.

Measuring prescription opioid misuse and its consequences.

AIMS: Prescription drug misuse in the USA increased during the 1990s to 2010. The epidemic stimulated the need new analytical strategies and techniques to understand the medications involved, user characteristics and other factors needed to address the epidemic. METHODS: A strategy of mosaic surveillance has evolved. Using real world evidence, the goal is to paint a more complete profile of a drug's real world misuse using triangulation-integrating results from multiple sources, where each approach has unrelated sources of bias. RESULTS: Research findings have been remarkably consistent across multiple data sources. The most commonly misused opioid medications: hydrocodone = oxycodone > methadone = buprenorphine = tramadol = fentanyl (prescription form) > morphine > hydromorphone = oxymorphone > tapentadol. This rank order is similar to the number of prescriptions dispensed for each product in the USA. In the USA, prescription opioid misuse started to decrease about 2011. Typically, multiple drugs are misused together, particularly in lethal cases. Immediate release formulations are more commonly misused than extended release formulations. The introduction of tamper resistant formulations to resist crushing were followed by a decrease in misuse of those products. CONCLUSIONS: The rapid expansion of opioid prescribing was accompanied by increasing misuse and mortality. Interventions such as prescription drug monitoring programmes, increased law enforcement and abuse deterrent formulations have been followed by decreases in misuse of most opioid analgesics.

Canine detection of volatile organic compounds unique to human epileptic seizure.

OBJECTIVE: Literature accounts of service dogs alerting patients prior to their seizures are a mix of historically poor quality data and confounding diagnoses. In a group of epilepsy patients, Canine Assistants and Florida International University characterized a unique scent combination of volatile organic compounds present during the immediate postictal period, but never at other times. The current study was designed to confirm prospectively if this unique scent, and potential biomarker, can: (1) be detected in an epilepsy monitoring unit (EMU), (2) whether this scent is present with nonepileptic seizures, and (3) whether this scent also precedes the clinical-electrographic seizure. METHODS: Following consent and approval, sweat samples taken from EMU admissions at Denver Health Medical Center were sent to Canine Assistants in Georgia. Their team of service dogs, who had been imprinted to recognize the unique scent, were then asked to process these sweat samples in a simple yes/no identification paradigm. RESULTS: Sixty unique subjects were enrolled over a two-year period. In the first part of this study, a total of 298 ictal sweat samples of 680 total observations were collected. The dogs had a 93.7% (OR: 14.89, 95% CI: 9.27, 23.90) probability of correctly distinguishing between ictal and interictal sweat samples. In the nonepileptic seizure population, 18 of the 19 NES events that were accompanied by sweat sample collections were not associated with identification of the unique seizure scent. In the second part of the study, in which subjects had samples collected every hour, dogs identified the unique seizure scent presence before 78.7% of all seizures captured, at a probability of 82.2% (OR: 4.60, 95% CI: 0.98, 21.69) of a positive detection predicting a seizure. The average duration of the warning phase of the scent was 68.2 min. The average duration of the tail phase of the scent faded after 81 min. SIGNIFICANCE: This study confirms the unique seizure scent identified by Canine Assistants and FIU may be collected and recognized by dogs trained to do so, in a prospective manner. A significant number of seizures appear to be associated with the unique scent presence prior to clinical-electrical onset of the seizure itself, and therefore further study of this biomarker is warranted.

The impact of the prescription opioid epidemic on young children: Trends and mortality.

BACKGROUND: Our objective was to describe trends and deaths in young children associated with opioid analgesics. METHODS: Analysis of pediatric exposures using the RADARS System Poison Center Program from July 1, 2010 through December 31, 2018. Cases involving a child < 6 years, with an exposure to one or more opioids: buprenorphine, fentanyl, hydrocodone, hydromorphone, methadone, morphine, oxycodone, oxymorphone, and tramadol. Poisson regression was used to model the shape of the time response curve. RESULTS: 48,560 cases were identified, median age 2 years (IQR 1.4, 2.0), 52.4 % male. The most commonly involved opioid was hydrocodone (32.5 %); buprenorphine and methadone had the highest exposure rates when adjusted for dispensed prescriptions (0.84 and 0.73 per 10,000 prescriptions). There were 28 deaths, methadone being the most commonly involved opioid (16). Exposures decreased significantly accounting for population (from 8.39 to 4.19 exposures per 100,000 children) and per prescription (from 0.33 to 0.25 exposures per 10,000 prescriptions). After adjustment for prescriptions, the exposure rate for hydromorphone and fentanyl increased over the study period, while buprenorphine had the greatest decrease in exposure rate. Among 28 deaths, 11 (39 %) were known or suspected to have been exposed, but medical care was not sought or was delayed. CONCLUSION: Pediatric opioid exposure rates by prescription and population decreased from July 2010 through December 2018. However, with over 48,000 exposures and 28 deaths, the opioid epidemic continues to impact young children. Many exposures including deaths were preventable. Continued improvements in prevention require a multifaceted approach.

Safety of School Playgrounds: Field Analysis From a Randomized Sample.

Research supports recess, however, playground injuries are prevalent with more than 200,000 cases per year requiring medical attention. School playgrounds are among the leading location for injury. The purpose was to identify the safety and risk factors of playground environments and impact attenuation characteristics of surfacing materials. Results demonstrated 46% playground spaces protected students from traffic. Results found 75% of playgrounds were exposed to full sun, and unitary surface materials were up to 49°F warmer than the air temperature. There was an increase in the probability of risk whether equipment height was over 9 ft for loose fill surfacing materials or over 6 ft for unitary surfaces. Loose strings or ropes looped over equipment were found on 23% of playgrounds. This study provides discussion and data pertaining to numerous aspects of playground safety. Strategies for school nurses are shared to shape policies and education for playground safety practices.

Comparative Rates of Mortality and Serious Adverse Effects Among Commonly Prescribed Opioid Analgesics.

INTRODUCTION: The epidemic of prescription opioid overdose and mortality parallels the dispensing rates of prescription opioids, and the availability of increasingly potent opioid analgesics. OBJECTIVE: The common assumption that more potent opioid analgesics are associated with higher rates of adverse outcomes has not been adequately substantiated. We compared the rate of serious adverse events among commonly prescribed opioid analgesics of varying potency. METHODS: Serious adverse events (SAEs; defined as death, major medical effect, or hospitalization) resulting from exposure to tablets containing seven opioid analgesics (oxycodone, hydrocodone, morphine, hydromorphone, oxymorphone, tapentadol, and tramadol) captured by the Researched Abuse, Diversion and Addiction-Related Surveillance (RADARS®) System Poison Center Program were evaluated from 2010 through 2016. Rates of SAEs were adjusted for availability through outpatient dispensing data and regressed on morphine milligram equivalents (MME). RESULTS: There were 19,480 cases of SAE during the 7-year study period. Hydrocodone and oxycodone contributed to 77% of SAE cases. Comparing rates of outcome by relative potency, a hierarchy was observed with hydromorphone (8.02 SAEs/100 kg) and tapentadol (0.27 SAE/100 kg) as the highest and lowest rates, reflecting a 30-fold difference among individual opioid products. SAE rate and potency were related linearly-SAEs increased 2.04 per 100 kg drug dispensed for each 1-unit rise in MME (p = 0.004). Linear regression of SAE/100 kg drug dispensed and drug potency identified that MME comprised 96% of the variation observed. In contrast, potency did not explain variation seen using other study denominators (prescriptions dispensed, dosage units dispensed, and the number of individuals filling a prescription). CONCLUSIONS AND RELEVANCE: Potency of a prescription opioid analgesic demonstrates a significant, highly positive linear relationship with exposures resulting in SAEs per 100 kg drug dispensed reported to poison centers. Potency should be carefully considered from both individual provider and public health perspectives.

Comparing ownership and use of bed nets at two sites with differential malaria transmission in western Kenya.

BACKGROUND: Challenges persist in ensuring access to and optimal use of long-lasting, insecticidal bed nets (LLINs). Factors associated with ownership and use may differ depending on the history of malaria and prevention control efforts in a specific region. Understanding how the cultural and social-environmental context of bed net use may differ between high- and low-risk regions is important when identifying solutions to improve uptake and appropriate use. METHODS: Community forums and a household, cross-sectional survey were used to collect information on factors related to bed net ownership and use in western Kenya. Sites with disparate levels of transmission were selected, including an endemic lowland area, Miwani, and a highland epidemic-prone area, Kapkangani. Analysis of ownership was stratified by site. A combined site analysis was conducted to examine factors associated with use of all available bed nets. Logistic regression modelling was used to determine factors associated with ownership and use of owned bed nets. RESULTS: Access to bed nets as the leading barrier to their use was identified in community forums and cross-sectional surveys. While disuse of available bed nets was discussed in the forums, it was a relatively rare occurrence in both sites. Factors associated with ownership varied by site. Education, perceived risk of malaria and knowledge of individuals who had died of malaria were associated with higher bed net ownership in the highlands, while in the lowlands individuals reporting it was easy to get a bed net were more likely to own one. A combined site analysis indicated that not using an available bed net was associated with the attitudes that taking malaria drugs is easier than using a bed net and that use of a bed net will not prevent malaria. In addition, individuals with an unused bed net in the household were more likely to indicate that bed nets are difficult to use, that purchased bed nets are better than freely distributed ones, and that bed nets should only be used during the rainy season. CONCLUSION: Variations in factors associated with ownership should be acknowledged when constructing messaging and distribution campaigns. Despite reports of bed nets being used for other purposes, those in the home were rarely unused in these communities. Disuse seemed to be related to beliefs that can be addressed through education programmes. As mass distributions continue to take place, additional research is needed to determine if factors associated with LLIN ownership and use change with increasing availability of LLIN.

Developing a playground injury prevention plan.

Playgrounds are a major source of unintentional injuries in the school environment. In fact, 80% of all injuries on public playground equipment happen at school. Thus, the need for developing a playground injury prevention plan is critical to provide safe educational outdoor environments for children. The S.A.F.E.trade mark framework for injury prevention is the first step in preventing playground injuries. This article highlights suggestions that school nurses can implement in creating an effective playground injury prevention program at their schools.

An investigation of school playground safety practices as reported by school nurses.

The purpose of this study was to investigate school playground safety practices. The study used a purposeful sample of school nurses who attended a playground safety workshop at the 2006 National Association of School Nurses annual conference. Seventy-five questionnaires were distributed, and 64 useable questionnaires were returned. The responses indicated that little attention is being given to providing safe playground environments in schools as measured by best practices of supervision, age-appropriate design, fall surfacing, and equipment maintenance. Participants pointed to the need for better supervision and supervision training, careful selection of age-appropriate equipment, maintaining adequate fall surfaces under the equipment, and ensuring that equipment is properly maintained and repaired. The study also revealed that school nurses believe they could play a role in playground injury prevention through the collection and analysis of injury data, communication to administrators about the need for comprehensive planning of the play environment, and becoming active members of playground safety committees.
